Tracking Two Subjects' Microbiomes for a Year, Researchers See Stability, Changes with Diet | GenomeWeb

NEW YORK (GenomeWeb) – Gut microbial communities are largely stable over time, though they can be shaped by host behaviors such as diet, according to a new sequencing-based analysis appearing in Genome Biology.

Researchers from the Massachusetts Institute of Technology and elsewhere tracked the gut microbiomes of two individuals for nearly a year while also collecting a host of behavioral data.
